My situation is like dude's, I think. In OmniGraffle 4 Pro, my objects all fit onto a single-page (1x1) canvas except for one document (where "spare" or unused network resource objects were stored just to the right of the canvas for easy access but so they wouldn't print). When opened with OmniGraffle 5 Pro, these documents were all spread over 4 (2x2) canvases as if every object was larger than before (which is different than dude's situation where his objects were smaller than before).

Its not a HUGE problem, but it will be a fair bit of work to fix all of my drawings... :(
